The crew of Discovery is a few hours away from undocking after almost nine days at the International Space Station.

The crew members will install the centerline camera before the undocking, which is scheduled for 6:42 a.m. CDT. That camera will help Commander Mark Kelly and Pilot Ken Ham fine tune the shuttle’s maneuvers as it backs away from the station.

After the shuttle undocks from the station, it will perform a flyaround of the newly expanded complex before conducting a final separation burn at 8:25 a.m.

Beginning at 10:12 a.m., the crew will conduct the late inspection of the shuttle’s heat shield using the orbiter boom sensor system in advance of Discovery’s return home on Saturday. Landing is scheduled for 10:15 a.m. central time at the Kennedy Space Center in Florida.

The crew woke up at 3:12 a.m. to “Centerfield” by John Fogerty. The song was played for Ham. The crew is scheduled to begin its sleep period at 6:32 p.m.
